Anderson Cooper holds hands with his handsome boyfriend Benjamin Maisani while hitting the red carpet at the 2015 Elton John AIDS Foundation’s Enduring Vision Benefit held at Cipriani Wall Street on Monday (November 2) in New York City.

“I’m proud of what we’ve done, but the journey is not complete. I won’t be proud until the journey is complete,” Elton said at the event (via Fox).

“We’ve come so far with treatment that actual treatment is prevention. You can reduce the load virus so low now in someone’s body that the risk of passing it on to someone else is practically zero,” David added. “What hasn’t changed is the mindset associated with knowing your status and testing and then living a positive happy life if you are HIV-positive and staying on the medications.”

Interestingly enough, Freddie was rarely asked about working with Kiefer on his promo tour leading up the the 24 season premiere, but here is what he did say:

In a Fox Press Interview: “I come to the table with a willingness to learn and you can tell Kiefer is someone who appreciates that and wants to give you everything he can in a hope that you’ll react to it. It’s this like focused chaos is how I would describe it and I really enjoy working with him, so on the serious side of the interview, as far as that goes it’s very rewarding.”

On Lopez Tonight: “With Kiefer, you have to be on point twenty-four hours a day. Well, twenty-four, I didn’t mean to say that, but you do.”

Kiefer‘s rep and a Fox official have both spoken out already to refute the claims and paint a different picture of the star’s behavior on set.

“Kiefer worked with Freddie Prinze, Jr. more than 5 years ago, and this is the first he has heard of Freddie‘s grievances,” a rep for the actor said in a statement. “Kiefer enjoyed working with Freddie and wishes him the best.”

An unnamed Fox official spoke to TMZ about the claims, saying Kiefer was “nothing but professional during the run of the show and is beloved by cast and crew.”

“It’s so out of left field, 5 years later. We wouldn’t have done another 24 if Kiefer were anything like Freddie described,” the Fox exec added.

Freddie Prinze, Jr. is opening up about his experience working on 24 as a guest star back in 2010, a job that almost made him quit acting.

“I did 24, it was terrible. I hated every moment of it,” Freddie told ABC News. “Kiefer [Sutherland] was the most unprofessional dude in the world. That’s not me talking trash, I’d say it to his face, I think everyone that’s worked with him has said that… I just wanted to quit the business after that. So, I just sort of stopped.”

“I went and worked for Vince McMahon at the WWE for Christ’s sake and it was a crazier job than working with Kiefer,” he added. “But, at least he was cool and tall. I didn’t have to take my shoes off to do scenes with him, which they made me do. Just put the guy on an apple box or don’t hire me next time. You know I’m 6 feet and he’s 5’4.”
